| Event Text AGREEMENT STATE REPORT - LEAKING SOURCE
The following was provided by the state via facsimile:
"On January 30, 2007 it came to [the licensee's] attention that a radioactive source on Paper Machine #3 is leaking. This source is listed on [the] Materials license (25709) under condition 9 : "Sealed Krypton 85 (85 Kr) sources ". The source is an ABB Industrial Systems Model TG-4, 1 Ci, s/n K-1331-R.
"The source is used as part of a scanning system on the paper machine. It is in a location not readily accessible to employees working in the area. Radiation levels at one foot around the source head are 0.1 mR/hour. The gas is leaking very slowly, as evidenced by a decrease over time in the process variable that it measures. The source has been labeled well with caution tape and a barricade tag is affixed to the tape.
"The plan for remediation is as follows:
" - A replacement source (loaner from ABB) is being shipped (2/1/07) and should arrive by overnight delivery (2/2/07). Upon arrival, [the] shipping department has been instructed to secure the new unit in a designated holding area for radioactive sources. The storage location is a heavy metal cabinet which is locked with a padlock to ensure the safety of the unit and of the workers. The cabinet is in an area not readily accessible to employees, in a building away from production areas.
" - The damaged source will stay in place in its frame on the paper machine until early next week when a specialist from ABB will arrive, repackage it and ship it back to ABB. The replacement source will be installed at that time.
" - A new source is in the process of being purchased. Delivery is expected in 8-12 weeks. At that time, [the state's] department will be notified there is a new source onsite."

"On February 20, 2007 at 1720 hours, the High Pressure Coolant Injection (HPCI) system was declared inoperable. During a system walkdown the HPCI Motor Speed Changer (MSC) was discovered energized. The MSC controls HPCI turbine speed during system startup and shutdown, and should not have been energized at the time of the walkdown. Additional troubleshooting determined the MSC was not functioning properly, rendering the HPCI system inoperable. This event is being reported as a condition that could have prevented fulfillment of a safety function in accordance with 10CFR50.72(b)(3)(v)(D) because the HPCI system is a single train system and the loss of HPCI could impact the plant's ability to mitigate the consequences of an accident. In accordance with Technical Specification Action 3.5.1.F, the Reactor Core Isolation Cooling (RCIC) system was confirmed operable. Further troubleshooting and engineering evaluations are continuing."
